HAY AND COTTON TRIER.

Specification of Letters Patent.

Patented June 25, rate.

Application filed September 27, 1917. Serial No. 193,611.

To all whom it may concern:

Be it known that I, HERMAN WATERHOL- TER, a citizen of the United States, and a resident of the city of Portland, county of Multnomah, State of Oregon, have invented a new and useful Improvement in Hay and Cotton Triers, of which the following is a specification.

The object of my invention is to provide an instrument for trying hay, cotton, and similar produce, also to adapt m'y instrument for being readily inserted in the body of a compact mass of producesuch, for example, as a bale of hayto any desired depth, and to assure that a sample of produce may be obtained in this way from any particular portion of the compact mass.

It is further my object that my instrument shall be especially adapted for attaining said result of withdrawing a sample of the product from any portion of the compact mass. I attain this object by making my instrument of a shank pointed at its extremity, and provided with horn-like 0ppositely disposed arms located at a point distant from the point of the shank, said horns tapering to a point and projecting inward in spiral form, and being spaced from the shank.

These details are shown in the accompanying drawings, in which:

Figure 1 is a side elevation of my device; and

Fig. 2 is a cross-section approximately taken on the line mw of Fig. 1.

The shank, a, is provided with a handle 5 and is tapered to a point, as at 0. At a' point distant from said pointed extremity the shank is provided with oppositely disposed horn-like arms d, e, which are tapered to a point and project inward in spiral form, being spaced from the shank, as more clearly shown in Fig. 2. Preferably the tapering extremity c is made at the point a, thusat the end of the taper, of greater crosssection than the cross-section of the shank a, and the roots of the horns d, 6 merge into said part of greater cross-section, as shown in Fig. 1.

My instrument is used as follows: The tapered extremity 0 is first pushed in, then I turn the instrument to the left, pushing it at the same time; in this way my instrument works itself into the mass of compact material like a screw, due to the described formation of the spiral arms cl, e. The shank being of suitable length, my instrument may in this way be driven into the mass to any desired depth. I then turn the instrument to the right until the arms at, e

have become filled with the material, which.

is noticeable because after the arms have become filled the instrument may be turned in the material much more easily. The inherent resiliency of the material will cause the portion lying about the shank inward of the extremity of the spiral arms OZ, 6 to snugly encompass the shaft and to become wedged between the arms and the shank. And when the trier is then pulled out, said arms will pull this portion of the material out with it.

I claim:

An instrument of the character described comprising a conical shank portion tapered to a point, and provided with arms at its inner end on opposite sides, said arms extending spirally and inwardly about the shank but spaced therefrom, their free ends substantially inclosing a space about said shank, whereby a sample of the material is held when the instrument is withdrawn from the mass.

HERMAN WATERHOLTER.
